Can you reclaim LBTT if a property in Scotland was uninhabitable when you bought it?

Introduction

Buyers sometimes discover after completion that a property is in far worse condition than expected. A common question is whether Land and Buildings Transaction Tax (LBTT) can be reclaimed if the building was not suitable for use as a dwelling on the effective date of the transaction.

This issue matters because, if a property was truly not suitable for use as a dwelling, it may be treated as non-residential for LBTT purposes. That can produce a lower tax charge and, in some cases, a refund. The difficulty is that the legal threshold is high, and poor condition alone is not enough.

The Question

A buyer in Scotland purchased a residential-looking property and later found serious defects. The reported problems included unsafe electrics, no gas connection, concerns over the water supply because of lead pipework, significant damp, rotten floorboards and roof defects requiring major work. The buyer wanted to know whether LBTT could be amended and reclaimed on the basis that the property was uninhabitable at the date of purchase, and whether the amendment had to be made personally or through a solicitor.

Nick’s Explanation

Nick’s main point was that LBTT is a self-assessed tax, so an amendment to the return may be possible if the buyer argues that the property was not suitable for use as a dwelling at the effective date.

He explained that Revenue Scotland has its own approach and guidance, and that Scottish practice is not simply the same as the position in England. In anonymised form, his reasoning was:

There may be an argument in the buyer’s favour if the condition of the property goes beyond normal repair, modernisation or refurbishment work. Because LBTT is self-assessed, an amendment can in principle be made within the permitted amendment window, although Revenue Scotland may well query it and ask the buyer to justify the position.

He also highlighted an important practical point: Revenue Scotland guidance is useful, but it is still guidance. It reflects the tax authority’s view, not a binding judicial ruling on every factual scenario.

Nick further noted that evidence would be critical. Photographs, surveys, electrical reports, contractor reports and other contemporaneous material showing the true state of the property at completion would all help support the claim.

On the procedural point, his explanation was that the buyer does not have to use the original conveyancing solicitor. Because LBTT is self-assessed, the buyer can seek an amendment directly or appoint a tax agent to do so.

The Law

LBTT is charged under the Land and Buildings Transaction Tax (Scotland) Act 2013. The tax treatment depends on whether the subject of the transaction is residential property or non-residential property at the effective date.

In broad terms, a building that is suitable for use as a dwelling is residential property. If it is not suitable for use as a dwelling at the effective date, the transaction may instead fall to be taxed at non-residential rates.

Revenue Scotland’s published guidance says that a dwelling may no longer be suitable for use as a dwelling where damage is beyond normal repair, modernisation or refurbishment work at the effective date. The guidance gives examples suggesting that a property is more likely to be unsuitable where:

• its structural integrity is compromised so seriously that, without significant works, it would be unsafe to live in; or
• making it suitable to live in would require demolition of the existing structure.

The same guidance also says that the following are generally examples of normal repair rather than evidence that a property is not a dwelling:

• fitting kitchen or bathroom facilities;
• repairing or replacing windows;
• paintwork;
• rewiring;
• roof repairs including re-slating, re-tiling or re-thatching;
• reconnection to utilities such as fitting a boiler or replacing piping to access water;
• repair or replacement of supporting timbers;
• repair work following water or fire damage;
• replacement of removed fixtures and fittings.

That distinction is important. A property can be in very poor condition and still remain a dwelling for tax purposes if the defects are treated as repairable works of a kind that do not alter its basic character as a residence.

In England and Wales, the condition threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. In an uninhabitable or not suitable for use case, that authority underlines that the test is demanding and that serious disrepair does not automatically mean the property stops being a dwelling. Although LBTT is a Scottish tax and Revenue Scotland is not bound to administer LBTT exactly as HMRC administers SDLT, the case is still relevant background when considering how high the condition threshold can be in modern tax litigation.

Analysis

The correct approach is to ask what the property was like on the effective date of the transaction, not what it looked like after later stripping-out works or after defects became more obvious during renovation.

Step 1 is to identify the exact defects existing at completion. Unsafe electrics, serious roof failure, structural danger, contamination or a legally unusable water supply may all be relevant. But each alleged defect needs evidence.

Step 2 is to separate true fundamental unsuitability from ordinary refurbishment. This is where many claims fail. A property may need extensive expenditure, but if the work is still classed as repair, replacement or reinstatement, Revenue Scotland may say it remained suitable for use as a dwelling in law.

Step 3 is to consider whether the defects made occupation unsafe or impossible in any real sense. For example:

• Unsafe electrics may help, especially if supported by a contemporaneous condemnation report.
• Lack of gas connection is usually less persuasive on its own, because many dwellings can exist without gas.
• Lead pipe concerns may help if there is evidence the water supply was not lawfully or safely usable at the time.
• Damp and rotten floorboards may support the overall picture, but often need to be shown to be severe enough to go beyond ordinary repair.
• Roof problems may be significant if they created immediate danger or required something close to reconstruction rather than routine repair.

Step 4 is to assess the strength of the evidence bundle. The best evidence is usually contemporaneous and independent, such as:

• electrical inspection reports stating the system was unsafe;
• surveyor or engineer reports;
• plumber or water authority evidence about the water supply;
• dated photographs and videos from the purchase date;
• auction or sales particulars;
• home report material;
• contractor quotations describing the nature of the works required.

Step 5 is to consider procedure. Because LBTT is self-assessed, an amendment may be possible within the statutory amendment period. In practice, even if an amendment can be filed without much explanation at the outset, Revenue Scotland may open an enquiry or otherwise challenge the basis of the amendment. The buyer should therefore assume that the position may need to be defended.

On the facts described, there is at least an arguable case, because the defects are not limited to cosmetic disrepair. However, the case is not automatically strong simply because the property was difficult or unsafe to occupy. The key question remains whether the condition crossed the legal threshold so that the building was not suitable for use as a dwelling at the effective date, rather than merely being a dwelling in need of major works.

Outcome

A buyer in this situation may be able to amend an LBTT return and argue that the property should have been taxed at non-residential rates because it was not suitable for use as a dwelling when bought.

However, success depends on evidence and on whether the defects go beyond normal repair, refurbishment or reinstatement. The threshold in condition cases is high. A property being empty for a long time, in poor condition, or expensive to fix does not by itself prove that it was not a dwelling for LBTT purposes.

The amendment does not have to be made through the original conveyancing solicitor. The buyer can usually deal with it personally or appoint an agent.

Practical Steps

If you are assessing a possible LBTT reclaim on this basis, the most useful next steps are:

• check the effective date of the transaction and confirm whether the amendment window is still open;
• obtain the filed LBTT return and confirm how the property was originally treated;
• collect dated photographs and videos showing the property’s condition at or very close to completion;
• obtain independent reports, especially electrical, structural, roofing and plumbing or water-supply evidence;
• gather any home report, auction pack, sales particulars and contractor quotations;
• prepare a chronology showing what defects existed on completion and why they made the property unsafe or unusable as a dwelling;
• compare the defects against Revenue Scotland’s guidance on what counts as normal repair;
• if filing an amendment, be ready for a challenge and keep the evidence organised from the outset.

Where the case depends on condition alone, it is sensible to test the evidence carefully before amending the return. The strongest cases usually involve clear structural danger or conditions requiring something close to rebuilding rather than ordinary repair.

Conclusion

It is possible to seek an LBTT refund where a Scottish property was not suitable for use as a dwelling at the purchase date, but the test is demanding. The issue is not whether the property was unpleasant, vacant or expensive to fix. The issue is whether, in law and on the evidence, it had ceased to be a dwelling at the effective date. If the defects truly went beyond normal repair, an amendment may be worth considering.
